Monsters in folklore are easy for us to comprehend. You can only kill a werewolf with a silver bullet, to stop a zombie for good, you have to destroy its brain, and vampires can’t enter your home without your permission. They also have pretty straightforward motivations. Werewolves: Animalistic rage. Zombies: Brains. Vampires: Blood. Human monsters have motivations that are a lot more opaque. What would possess someone to kidnap a woman in broad daylight? To break into a home in the middle of the night to kill the strangers inside? What if no one saw anything? How do you catch a ghost?
